******************************************************************** * IBM DS4000 Fibre Hard Disk Drive and ESM Firmware Update Pack * * Readme.txt Version 1.45 07/11/2005 * ******************************************************************** 1.0 Overview 2.0 Change History 3.0 version History 4.0 Installation and Setup Instructions 5.0 Configuration Information 6.0 Unattended Mode 7.0 Web Sites and Support Phone Number 8.0 Trademarks and Notices 9.0 Disclaimer 1.0 Overview _____________ 1.1 Overview of this code The IBM DS4000 Fibre Hard Disk and ESM Update Pack contains ESM and hard disk drive firmware updates for FAStT200s, FAStT500s, DS4300s, DS4400s and DS4500s with EXP500s, EXP700s and EXP710 attached. The microcode(firmware) level for the EXP500 ESM is 9166. The microcode(firmware) level for the EXP700 ESM is 9327. IMPORTANT: This version of the ESM firmware or version 9327 is required for the DS4000 controller firmware version 06.xx.xx.xx or higher. The DS4000 storage subsystem with controller firmware version 06.xx.xx.xx or higher might not recognize EXP700 with ESM firmware 9324 or earlier. The version 9327 ESM firmware incorporate new additional maintenance fixes since the release of the version 9326 ESM firmware. The microcode(firmware) level for the EXP710 ESM is 9631. The DS4000 storage subsystem controller firmware version 06.1x.xx.xx or higher is required for EXP710 drive expansion enclosure attachment. IMPORTANT: FRUs are starting to ship with these levels of ESM Firmware. If the ESMs are not updated when the FRUs arrive at the higher level, the down level ESM will need updating at that time. This release contains the following firmware for IBM Hard Disk Drives: ST39103FC B325 (unchanged) ST318203FC B325 (unchanged) ST136403FC B325 (unchanged) ST318304FC B338 (unchanged) ST336704FC B338 (unchanged) ST173404FC B338 (unchanged) ST336605FC B347 (unchanged) ST373405FC B347 (unchanged) ST318451FC B934 (unchanged) ST318452FC B94a (unchanged) ST336752FC B94a (unchanged) ST318432FC B949 (unchanged) ST336732FC B949 (unchanged) ST318453FC B95B ST336753FC B95B ST373307FC B35C ST336607FC B35C ST3146807FC B35C ST373453FC B95B HUS103073FLF21 JFQ4 HUS103030FLF21 JFQ4 HUS103014FLF21 JFQ4 IMPORTANT: There are two versions of the drive firmware download files. These two versions are placed in the HDD_SM8x_format and HDD_SM9x_format folders. The version of the currently installed controller firmware in the DS4000 storage subsystem dictates which version of the drive firmware files to use for updating the drive firmware. If the current DS4000 storage subsystem firmware version is of 06.xx.xx.xx, use the firmware files in the HDD_SM9x_format folder. Otherwise, if the current DS4000 storage subsystem firmware version is of 05.xx.xx.xx and earlier, use the firmware files in the HDD_SM8x_format folder instead. 1.2 Limitations The minimum controller firmware levels for this update are: 7.10/04.01 Client Software/Firmware: Model Type Appware/Bootware NVSRAM 3552-1RU 04.01.02.33/04.01.02.03 NV3552R710NT012 3552-1RX 04.01.02.33/04.01.02.03 NV3552R710NT012 3542-1RU 04.01.02.34 NV3542R710NT019 3542-1RX 04.01.02.34 NV3542R710NT019 3542-2RU 04.01.02.34 NV3542R710NT020 3542-2RX 04.01.02.34 NV3542R710NT020 8.21/05.21 Client Software/Firmware: Model Type Appware/Bootware NVSRAM 3552-1RU 05.21.05.10/05.00.02.00 CNV3552R820NT012 3552-1RX 05.21.05.10/05.00.02.00 CNV3552R820NT012 1742-1RU 05.21.05.10/05.00.02.00 CNV1742R820NT012 1742-1RX 05.21.05.10/05.00.02.00 CNV1742R820NT012 3542-1RU 05.21.12.10 CNV3542R820NT029 3542-1RX 05.21.12.10 CNV3542R820NT029 3542-2RU 05.21.12.10 CNV3542R820NT030 3542-2RX 05.21.12.10 CNV3542R820NT030 8.3x/05.3x Client Software/Firmware: Model Type Appware/Bootware NVSRAM 3552-1RU 05.30.19.00/05.30.03.00 N3552F500R830V04 3552-1RX 05.30.19.00/05.30.03.00 N3552F500R830V04 1742-1RU 05.30.19.00/05.30.03.00 N1742F700R830V04 1742-1RX 05.30.19.00/05.30.03.00 N1742F700R830V04 3542-1RU 05.30.19.00 N3542-1RUR830V05 3542-1RX 05.30.19.00 N3542-1RUR830V05 3542-2RU 05.30.19.00 N3542-2RUR830V06 3542-2RX 05.30.19.00 N3542-2RUR830V06 1742-90U 05.30.19.00/05.30.03.00 N1742F900R830V05 1742-90X 05.30.19.00/05.30.03.00 N1742F900R830V05 1722-60U/60X Standard 05.34.04.00 N1722F600R834V01 1722-6LX 05.34.04.00 N1722F60LR834V04 8.40/05.40 Client Software/Firmware: Model Type Appware/Bootware NVSRAM 1742-1RU 05.40.15.00/05.40.05.00 N1742F700R840V04 1742-1RX 05.40.15.00/05.40.05.00 N1742F700R840V04 1742-90U 05.40.15.00/05.40.05.00 N1742F900R840V03 1742-90X 05.40.15.00/05.40.05.00 N1742F900R840V03 1722-60U 05.40.15.00 N1722F600R840V05 9.1/06.10 Client Software/Firmware: Model Type Appware/Bootware NVSRAM 1742-1RU/1RX 06.10.11.00/06.10.03.00 N1742F700R910V03/I1742F700R910V04 1742-90U/90X 06.10.11.00/06.10.03.00 N1742F900R910V03/I1742F900R910V04 1722-60U/60X Base 06.10.11.00 N1722F600R910V03 Turbo 06.10.11.00 N1722F600R910V03/I1722F600R910V05 9.12/06.12 Client Software/Firmware: Model Type Appware/Bootware NVSRAM 1742-1RU/1RX 06.12.03.00/06.10.04.00 N1742F700R912V05 1742-90U/90X 06.12.03.00/06.10.04.00 N1742F900R912V06 1722-60U/60X Base 06.12.03.00 N1722F600R912V05 Turbo 06.12.03.00 N1722F600R912V05 9.14/06.14 Client Software/Firmware: Model Type Appware/Bootware NVSRAM 1815-82A/84A 06.14.19.00 N1815D480R914V05.dlp 82H/84H 9.15/06.15 Client Software/Firmware: Model Type Appware/Bootware NVSRAM 1815-82A/84A 06.15.11.00 N1815D480R914V05.dlp 82H/84H Updating ESM firmware requires downtime (no host I/O) if the DS4000 controller firmware level is 05.21.xx.xx or lower. In addition, a special version of the Storage Manager SMclient program called the Storage Manager Field Tool must be used to download ESM and hard disk firmware/Microcodes. Updating Hard Disk Microcode requires downtime (no host I/O). 1.3 Enhancements See Section 2.0 Change History. 1.4 Level of Recommendation IBM considers this update to be highly recommended for all customers. a. The 9166 ESM firmware is needed for the EXP500 drive enclosure ESMs to prevent accidental corruption from downloading the wrong firmware to the ESM. In the environments where there are EXP500s and EXP700s enclosures attached to the same DS4000 storage subsystem, it is IMPERATIVE that all EXP500s ESMs are updated to 9166 before the EXP700 ESM firmware is applied. b. The 9327 ESM firmware is needed for the ESM of the EXP700 drive enclosure ESMs to incorporate the maintenance fixes since the release of the 9326 EXP700 ESM firmware. It is preferred over the version 9326 ESM firmware that must be loaded into the EXP700 drive enclosures before the controller firmware version 06.1x.xx.xx is downloaded into the DS4000 storage subsystem because the DS4000 storage subsystem with controller firmware version 06.xx.xx.xx or higher might not recognize EXP700 enclosures with ESM firmware version 9324 or earlier. c. The 9631 ESM firmware is needed for the EXP710 drive enclosure ESMs to incorporate maintenance fixes. d. The fibre channel drives with the following Product ID strings - ST318453FC, ST336753FC, ST373453FC, ST373307FC, ST336607FC, ST3146807FC, HUS103073FLF21, HUS103030FLF21 and HUS103014FLF21 need to be updated with the latest drive firmware files in this web download package. These firmware files contained the latest maintenance fixes to correct several field problems including performance in certain IOs load scenario. The EXP500, EXP700 and EXP710 ESM FRU replacements will also be updated to the current levels in this release (9166, 9327 and 9631 respectively), so if the surviving ESM in an EXP500, EXP700 or EXP710 is not updated before the first ESM failure, downtime might be scheduled to update it after the replacement is inserted. If the new ESM is installed before the surviving ESM is updated, the DS4000 controller will register an ESM hardware or firmware mismatch error in the Recovery Guru. The new ESM will function; but long term operation with a mismatch ESM firmware in a EXP drive expansion enclosure is not recommended. Customers who have updated to DS4000 Storage Manager 8.3 or higher and controller firmware 05.30.xx.xx or higher can update ESMs firmware online with no downtime if both ESMs are functional and ONLY ONE EXP enclosure at a time is selected in the ESM firmware download window for ESM firmware updating. IBM strongly recommends applying both the HDD and ESM firmware at the next possible maintenance window. 1.5 Dependencies IMPORTANT: Always check the DS4000 storage subsystem controller firmware README for any required minimum version of the attached drive expansion enclosure ESM firmware for that particular controller firmware release. Update the ESM firmware using either the DS4000 Storage Manager Field Tool (DS4000 storage subsystem with controller firmware version 5.21.xx.xx or earlier) or the DS4000 Storage Manager SMClient program (DS4000 storage subsystem with controller firmware version 5.3x.xx.xx or later). Be sure to follow the following list of prerequisites before updating hard disk or ESM firmware. - For Hard Disk Drive firmware updates, ensure that all activity to the controller is stopped. - For ESM updates, all activity must be stopped if the controllers are at any firmware below 05.30.xx.xx. - For ESM updates, all EXP500s need to be updated to 9166 before EXP700s can be updated to 9327 (or 9326). Note: Not all DS4000 storage subsystems support the latest controller firmware version 06.1x.xx.xx. The latest controller firmware versions for the FAStT200 and FAStT500 storage subsystems are 05.30.xx.xx. In addition, the DS4300 storage subsystem with single controller options can be updated to latest firmware version of 05.34.xx.xx only. If you are unsure about the sequence of firmware updates for various components in the DS4000 storage subsystem configuration, please call IBM Support at 1-800-IBM-SERV (1-800-426-7378) before proceeding with the firmware upgrades. ___________________ 2.0 Change History ___________________ 2.1 IBM DS4000 Hard Disk and EXP500/700/710 ESM Update Program Version 1.45 Updated the EXP710 ESM Firmware to 9631 to incorporate maintenance fixes. - Fix the notification problem between the Switch-JBOD chips (SOC) in the EXP710 ESM during the DS4000 storage subsystem powering up that might caused the EXP710 ESMs to falsely believe they were not connected to other EXP710 ESMs. This in turn lead the DS4000 controllers to think that the EXP710 drive enclosures were not properly clustered together (83970). - Fix the problem that might cause drive(s) to report a loss of redundancy after hot swapping the EXP710 ESMs as part of a ESM replacement procedure. The problem was caused by the SerDes PLLs on the SOC chips in the EXP710 ESMs locking onto the wrong frequency at SOC power-up, causing loss of access to drive(s). As part of this change to allow the EXP710 ESM time to boot up and stabilize after being hot-plugged, the EXP710 ESM firmware will now wait 12 seconds before unbypassing the external SFP connections. One visible external indicator of this change is that the EXP710 ESM SFP ports will flash for 12 seconds while they are held in bypass, until they are released to "automatic" /normal mode. (85965/TD_PT5331) Updated drive firmware for the fibre channel drives with the "Product ID" strings ST318453FC, ST336753FC and ST373453FC to B95B and ST373307FC, ST336607FC and ST3146807FC to B35C to incorporate enhancements and maintenance fixes. The list of enhancements are as followed: 1. Corrected & Updated List of Sense Key Error Codes that need trigger to save to disc of Log Page 3Ah to improve the amount of data collected during failures. 2. Fix drive false errors reporting while running background write/read test 3. Incorporate Drive State Dump feature which is controlled through mode page setting and can be initiated by SCSI command. 4. Change format of Inquiry page C4h to comply with IBM Manufacturing test enhancements 5. Add Enable ECHO_FAULT_LED_TO_ACTIVE feature so that the HDD drive fault blink codes are reported on HDD Activity LED instead of Fault LED. This will allow customers and field service to read the blink codes of faulty drives to assist with drive failure analysis. This new version of drive firmware also contains various maintenance fixes for field problems. Only the major severity problem fixes are listed below: 1. No Response to PLOGI 2. Drive goes bypass with no/rapid flashing of activity LED 3. Assert when busying port during CRC triggered abort 4. Target busy for >20 seconds after receiving LIP FF with WCE=0 5. Prediction not disabled following ABTS 6. No sense data after a check status 7. Need extra free retries for ROA issue causing 09/8000/C3 8. Format Immediate causes other commands to hang. 9. Port Busy Assert After Write merge Abort 10. Fix cleaning up of ALU Buffer Parity error prior to flashing LED 0x19 11. Assert Failure: Dirty Segment Flags was set upon releasing segment . This problem has been reported by some DS4000 customers 12. RLA algorithm overflow caused read command with long transfer to timeout. 13. Corrupted DRAM read cause link service command timeout 14. Drive Hanging due to not reselecting for a read command or hanging not sending the data for a read command 15. Assert with disk transfer ctb=null when a paused WCE restarts. 16. Targeted LIP Reset during data-in phase causes target to OPN itself.....WCE must be enabled. 17. Performance degradation on Write / Read until Reset is received. Updated drive firmware for the fibre channel drives with the following Product ID strings HUS103073FLF21, HUS103030FLF21 and HUS103014FLF21 to JFQ4 to incorporate maintenances fixes for the several low- severity problems. The most severe problem fixes are listed below: - drive hung after the OPN retry time-out occurred and the next queued command the was fetched (dequeued) from the command queue is the write command. - 60s timeout occurred for the random read/ write command when large number sequential reads are received and get full cache hits in different segments. - problem that could degrade the write sustain rate and 1Gbps write sequential performance. - drive went into degraded mode and reported 04/4400 forever after being reboot three times to recover from the drive S-RAM correction. Version 1.44 Updated the EXP710 ESM Firmware to 9629 to incorporate maintenance fixes. - 81272 Drive-side timeouts with EXP710 on the DS4300 mreg (2) - 82461 (C259426) : drives do not spin up when incorrectly connecting EXP710/EXP700 in non-clustered setup (2) - 83528 (WIC~80458) two drive enclosure IDs of 0 on the loop after doing simulated ESM pulls (2) - 79542 Drive side timeouts during benchmarks when using EXP710 enclosures Updated the EXP700 ESM firmware to 9327 to incorporate maintenance fixes. - 82950 LIP not generated as drives join the loop...ESM does not complete diagnostics - 83188 2G ESM becomes unresponsive on fibre loop when peer has I2C failure - 83211 2G ESM sets SES bypass bits incorrectly when drive bypasses itself - 83812 Power cycle EXP700 trays caused loop stability issue due to improper LISM Version 1.43 Document the correct behavior when one inserts an ESM that does not have same ESM firmware version as the surviving ESM in the drive expansion enclosure in section 1.4 of the README file. Modify section 1.5 of the README file to show the new IBM recommended firmware upgrade sequence for the ESMs, controllers and hard drives in an DS4000 storage subsystem configuration. Version 1.42 Repackage the Drive firmware files so that they are recognized as the drive firmware files by the DS4000 storage subsystem with controller firmware version 06.xx.xx.xx installed. Version 1.41 Updated EXP700 ESM Firmware to 9326 to correct memory corruption issue that caused the ESM port name to change on the loop, resulting in I/O errors. The memory corruption was occurring when the ESM sent a response frame that didn't get taken off the loop for any reason and came back to it, which might happen if one of the ports on the ESM or controller tray were bypassed at the right time. This was fixed with new Vitesse libraries. The new Vitesse libraries also fixed a problem where the Vitesse code was occasionally incorrectly removing some spawned tasks and preventing them from firing, which was causing problems with loop diagnostics. There were some additional changes to help make sure we report loop diagnostic failures correctly by adding retries to the code for turning on fault LEDs in case of temporary I2C failures. The new Vitesse libraries also fixed some issues we were seeing with unexpected LIPs on the loop under heavy I/O loads. 2.2 IBM DS4000 Hard Disk and EXP500 ESM Update Program Version 1.40 Updated EXP700 ESM Firmware to 9324 to correct false fan and temperature errors, correct problems where the drives in bays 11-14 would not spin up at power up, correct other drive side issues, and provide support for copper GBIC cabling for use only with the SAN Integrated subsystem. Updated EXP500 ESM Firmware to prevent accidental corruption from downloading the wrong firmware to the ESM. In environments where there are EXP500s and EXP700s in the same controller, it is IMPERATIVE that all EXP500s ESMs are updated to 9166 before the EXP700 ESM firmware is applied.

ESM firmware 9150 is the initial firmware ___________________________ 4.0 Installation and Setup ___________________________ 4.1 Applying updates on DS4000 controllers with 04.01.xx.xx or 05.2x.xx.xx firmware To apply ESM Updates, use the IBM DS4000 Field Tool v8.21. See the README included with that utility for directions on how to apply updates. The utility can be found on the firmware update page at: http://www-1.ibm.com/support/docview.wss?uid=psg1MIGR-40120 Ensure that all activity to the controllers is stopped while performing ESM firmware updates with controller firmware 04.01.xx.xx or 05.2x.xx.xx. Allow approximately 5-10 minutes per ESM to complete the firmware update. This will require downtime. 4.2 Applying updates on DS4000 Controllers with 05.3x.xx.xx firmware or higher. To apply ESM updates use the DS4000 Storage Manager Client 8.3, 8.4 or 9.1. See the on-line help included in the DS4000 Storage Manager Client. Application of ESM firmware on DS4000 Controllers with 05.3x.xx.xx firmware or higher should be performed by choosing only one EXP at a time, and done during non-peak utilization periods. If you have a maintenance window with downtime, you can stop all I/Os and update all the ESMs at one time. Allow approximately 5-10 minutes per ESM to complete the firmware update. 4.3 Ensure that all activity to the controllers is stopped while performing hard disk drive (HDD) firmware updates with all levels of controller FW. Allow approximately 3-5 minutes per HDD to complete the firmware update when the DS4000 storage subsystem controller firmware is at 05.xx.xx.xx or earlier. The DS4000 storage subsystems with controller firmware 06.xx.xx.xx or higher can update the drive firmware of all the drives in a given DS4000 configuration for up to four different drive models at the same time; Thus, one could update all of the drives in the DS4000 configuration in the same amount of time that is needed to upgrade a single drive in the DS4000 storage subsystem with controller firmware version 05.xx.xx.xx or earlier. THE DRIVE FIRMWARE UPDATE WILL REQUIRE DOWNTIME. However, the DS4000 storage subsystems with controller firmware 06.xx.xx.xx installed can update all drives in a configuration for up to four different drive types at the same time. IMPORTANT: In the DS4000 storage subsystems with FC/SATA intermix premium feature enable, do not download the drive firmware to both SATA-technology hard drives and Fibre Channel-technology hard drives at the same time. Complete the drive firmware download to all of the drives of a drive technology (either SATA or FC) before downloading the drive firmware to the drives of the other drive technology (either FC or SATA). ______________________________ 5.0 Configuration Information ______________________________ 5.1 There is no special configuration required with the IBM DS4000 Fibre Hard Disk Drive and ESM Updates. ____________________ 6.0 Unattended Mode _____________________ 6.1 See the appropriate application tools for any possible unattended mode operations. _______________________________________ 7.0 WEB Sites and Support Phone Number _______________________________________ 7.1 IBM TotalStorage™ Disk Storage Systems Technical Support web site: http://www.ibm.com/servers/storage/support/disk/ 7.2 IBM TotalStorage™ Marketing Web Site: http://www.ibm.com/servers/storage/disk 7.3 If you have any questions about this update, or problem applying the update go to the following HelpCenter World Telephone Numbers URL: http://www.ibm.com/planetwide __________________________ 8.0 Trademarks and Notices __________________________ 8.1 The following terms are trademarks of the IBM Corporation in the United States or other countries or both: IBM DS4000 FAStT ToTalStorage™ the e-business logo xSeries pSeries HelpCenter Microsoft, Windows, and Windows NT are trademarks of Microsoft Corporation in the United States, other countries, or both.
